Chat Box - option to close

It would be great to be able to close the chat box while one is working. It pops up over and over again and obstructs the working view. I have contacted Support and they say they understand. But truly, it is distracting and slows one down. The faster people can work the more people will publish. The website needs to be smooth and easy all around. A simple question mark will do. Those who need it can opt into it. Thank you.
